Bankart RepairBy: Abbie Mitchell, Brian Bartow,

Jordan Anderson, & Tyler Pecha

What is a Bankart Lesion?◦ A Bankart lesion is a traumatic detachment of the glenoid labrum .

Most common cause: Dislocation of the shoulder.

◦ At the time of original injury, the humeral head is forced out anteriorly and inferiorly, first stretches the anterior capsule and the inferior glenoid ligament. As a result of the traction from the inferior glenoid ligament, the fibrous labrum is

pulled off from the anterior rim of the glenoid.

◦ Seen in over 85% of cases after a traumatic anterior dislocation.

◦ More common in younger (under 30 years old) individuals.

◦ The inferior glenoid ligament is the most important stabilizer of the shoulder; The stretch of the ligament and the resulting Bankart lesion results in shoulder instability.

When is the procedure performed?

◦ Surgery is recommended with younger than middle age individuals who lead active lifestyles.

◦ Biggest factor is chance for repeat dislocations. Other factors: Patient’s pain, instability, lifestyle, and

activities. ◦ Approximate percentage for re-dislocation:

Under the age of 20 = 90% Between 20-30 years old = 75% Between 30-40 years old = 30%

Background

Procedure:

Traditionally, most orthopedic surgeons would not choose to operate on a patient after a first dislocation. Rather, after a brief period of immobilization, followed by physical therapy, the patient would gradually resume their normal activities. If the patient sustained a second, or recurrent, dislocation, then surgery was considered.

More recently, there is good scientific evidence to support early surgery, especially in young patients who are at a high risk for re-dislocation.

Background

Procedure:

Can be completed arthroscopically or via open surgical technique.

Involves reattachment and tightening of the labrum and ligaments of the shoulder.

Usually done using sutures and small bone anchors.

Surgeon will also smooth out rough edges of labrum.

Procedure:

Procedure:

AROM – guarding, compensatory movements, scapular kinematics (delayed until active motion is allowed).

PROM – guarding, pain check incision – color, temperature, healing process, signs of infection,

bandaging palpation pain swelling neurological changes – temperature, sensation, weakness mechanism of initial injury medical/surgical/injury history medication compliance PLF, CLF occupation, hobbies, recreational activities living environment patient goals

Examination

inter- and intra-rater agreement for 5 different methods of assessing shoulder range of motion in 6 directions:◦ visual estimation

inter: 0.57-0.70 intra: 0.59-0.67

◦ goniometry inter: 0.64-0.69 intra: 0.53-0.65

◦ still photography inter: 0.62-0.73 intra: 0.56-0.61

◦ stand and reach inter: 0.74 intra: 0.49

◦ hand behind back reach inter: 0.26-0.39 intra: 0.14-0.39

fair-good reliability found for all methods except hand behind the back reach (poor)

Signs & Symptoms

Bankart Lesion:◦ is an avulsion of the anteroinferior glenoid labrum

at its attachment to inferior glenohumeral ligament (IGHL) complex; lesion is felt to result from anterior shoulder dislocation and is felt to be primary lesion in recurrent anterior instability.

Hill-Sachs lesion:◦ impression fracture of the humeral articular surface

caused by translation of the humeral head over the glenoid rim. Found in 85% of anterior dislocations. If >25% of the articular surface is involved allograft or autograft bone graft to repair the defect is indicated

Differential Diagnosis

SLAP (superior labral anterior posterior tear)

◦ Acquired Posterior Capsular Contracture in throwing athletes leads to high torsional and shear stress on the posterosuperior labral in the late-cocking phase of throwing, which can produce a posterior SLAP lesion. Throwers may feel sharp pain in the extreme abduction/ER position followed by "dead arm" sensation and loss of throwing velocity.

◦ History of falls directly on shoulder, downward force on outstretched arm, or sudden eccentric force on a contracting biceps.

Differential Diagnosis

Rotator Cuff Tear (RTC) Anterior-Inferior Glenohumeral Instability

◦ Athletes: instability may occur with repetitive external rotation with the arm in abduction (apprehension position).

ALPSA: ◦ anterior labroligamentous periosteal sleeve avulsion;

medialized Bankart with medial displacement of the torn anterior labrum.

Perthes lesion: nondisplaced labral tear GLAD lesion:

◦ glenolabral articular disruption: nondisplaced anterior labral tear associated with articular cartilage injury.

Differential Diagnosis

CORRELATION BETWEEN BANKART AND HILL-SACHS LESIONS IN ANTERIOR SHOULDER DISLOCATION◦ A total of 61 patients had an MRI◦ The MRI scans were reviewed and subsequently confirmed by

a radiologist to show the presence or absence of Bankart andHill-Sachs lesions

◦ 73% had a Bankart lesion and 67% had a Hill-Sachs lesion on MRI

◦ 64% of those with a Bankart lesion had Hill-Sachs lesions◦ 70% of those with Hill-Sachs lesions had a Bankart lesion◦ The correlation between Bankart lesion and Hill-Sachs lesion

showed that if one of the lesions was identified, the chance of the other being present was more than two-and-a-half times as likely

Differential Diagnosis

Diagnosis/Prognosis Guide to PT Practice- PT Diagnosis

◦ 4I- Impaired Joint Mobility, Motor Function, Muscle Performance, and Range of Motion Associated with Bony or Soft Tissue Surgery

Prognosis◦ Following physician/PT directions both open and

arthroscopic repairs have a good prognosis◦ Recurrance:

Marquardt, et al: 5.6% failure rate (arthroscopic) Gartsman et al: 7.5% failure rate (arthroscopic) Freedman et al: 12.6% arthroscopic vs 3.4% open

Failure to identify bony lesions through arthroscopy (4% failure rate when bony lesions excluded)

Problem list/Goals Problem list

◦ Pain◦ Decreased ROM◦ Decreased Strength◦ Swelling

Goals◦ Goals will be related to function and will address

problems from problem list.◦ Will address different parts of problem list based

on phase of recovery.

Sample Goals Phase one (weeks 0-6):

◦ Following PT intervention, pt will report decrease in pain to 2/10 at rest, in order to sleep through the night, within 2 weeks.

Phase two (weeks 6-12):◦ Following PT intervention, pt will achieve full shoulder

AROM within 10 weeks in order to be independent in ADL’s.

Phase three (weeks 12+)◦ Following Pt intervention, pt will achieve equal

strength, all motions bilateral shoulders, within 16 weeks in order to return to full work responsibilities as a mechanic.

Timeline Stages of Tissue Healing!

◦ Who knows them?

Timeline Stages of tissue healing

◦ Inflammatory stage (0-2 weeks)◦ Proliferation/Repair stage (days-6 weeks)◦ Maturation/Remodeling (up to 2 years!)

General Timeline◦ Return to strenuous work duties

Physician dependent Generally around 4 months

Inpatient care

Today this is an outpatient surgery

Outpatient careComparison of 4 different Bankart Repair protocolsConsensus among protocols Modalities as needed for pain/swelling Sling until week 6 typically ROM

◦ Begin pain-Free PROM around week 2 Brigham and Women’s Hospital: No shoulder movements

of any kind until week 4. Very slow progression of passive ER in scapular plane or

at 90 degrees abduction. ER last to regain full motion◦ Joint Mobilizations

Avoid anterior glides to protect surgical repair◦ No AROM until around week 6◦ Full AROM around week 10

Strengthening◦ Pain-free RTC isometrics around week 2◦ Begin isotonic shoulder strengthening around week 6

Slow progression of strengthening exercises Avoid aggressive strengthening exercises that

place stress on anterior capsule (i.e. bench press, push-ups

◦ Equal strength bilaterally around week 14-20 Return to sport/strenuous work duties

◦ Physician dependent◦ Pain Free shoulder Function without signs of instability◦ Full AROM◦ Equal Strength Bilaterally

Outpatient Care

Outpatient care Take Home Message

◦ Slow and conservative rehabilitation◦ Number one priority

Protection of healing tissues!

Home Program Post-op

◦ Ice as needed for pain/swelling◦ Pendulums

Emphasis on correct form to ensure passive movements

◦ AAROM elbow, wrist, hand◦ Wound care

Active Motion phase◦ HEP of specific strengthening/stretching activities◦ Progression of strengthening exercises as tissue

healing occurs

Patient Education Avoid active motion during first 6 weeks Warn pt of over-compliance Mechanism of injury

◦ Re-emphasize mechanism as same mechanism is what will cause surgical repair to fail I.E. forced external rotation and extension

POC◦ Including problem list, goals, timeline, prognosis

HEP and progression of HEP
